Richard Tsien is the Druckenmiller Professor of Neuroscience, Chair of the Department of Physiology and Neuroscience, and Director of the NYU Neuroscience Institute at New York University Medical Center, and also an emeritus faculty of Stanford University School of Medicine. He is a member of the National Academy of Sciences and the American Academy of Asrts and Sciences. The Tsien Lab works in many areas of neuroscience, with multiple approaches, but there is a unifying question: how are neuronal networks attuned to meeting the demands of information processing in the brain?
